Srinivasa Ramanujan was a great Mathematician, who became world famous at the age of twenty six. He was born at Erode in Tamil Nadu on 22 December 1887.
Ramanujan could not complete his college education because of illness. He was so interested in mathematics that he learned on his own. He found out new formulas for solving mathematical problems and wrote articles about them. Professor Hardy a scientist in the Cambridge University saw one his article and impressed by his knowledge, took Ramanujan to England.
Ramanujan was considered as the master of theory of numbers. The most outstanding of his contributions was his formula for p (n), the number of 'partitions' of 'n'.

He returned to India in 1919 and began Research. He passed away on 26 April 1920. Government of India issued a commemorative stamp in his honour. Indian National Science academy and many other scientific institutions in India are giving various awards in memory of this brilliant mathematician.
